BackgroundMalaria control and elimination are challenged by diversity and complexity of the determinants on the international border in the Great Mekong Sub-region. Hekou, a Chinese county on the China–Vietnam border, was used to document Chinese experiences and lessons for malaria control and elimination.MethodsThe design was an ecological study. Malaria burden before 1951 and procedures of 64 years (1952–2015) from malaria hyperendemicity to elimination are described. Single and bilinear regression analysis was utilized to analyse the relationship between the annual malaria incidence (AMI) and gross domestic product (GDP), urbanization rate, and banana planting area (BPA).ResultsThere was a huge malaria burden before 1951. AMI was reduced from 358.62 per 1000 person-years in 1953 to 5.69 per 1000 person-years in 1960. A system of primary health services, comprising three levels of county township hospitals and village health stations maintained malaria control and surveillance activities in changing political and social-economic settings. However, potential under-reported of malaria and market-oriented healthcare led to a malaria epidemic in 1987. Strong political commitment reoriented malaria from a control to an elimination programme. High coverage of malaria intervention and population access to intervention was crucial for malaria control and elimination; meanwhile, AMI was closely associated with socio-economic development, correlation coefficients (R) −0.6845 (95% CI −0.7978, −0.6845) for national GDP, −0.7014 (−0.8093, −0.7014) for national urbanization rate and −0.5563 (−0.7147, −0.3437) for BPA.ConclusionsMultifactor, including political commitment, effective interventions, social and economic development and changing ecological environment, and the complicated interactions between these factors contribute to malaria elimination in Hekou County.Electronic supplementary materialThe online version of this article (doi:10.1186/s12936-017-1709-z) contains supplementary material, which is available to authorized users.
Study design:
Case series.
Background:
Robot-assisted rehabilitation mediated by exoskeletal devices is a popular topic of research. The biggest difficulty in the development of rehabilitation robots is the consideration of the clinical needs. This study investigated the usability of a novel cable-driven exoskeletal robot specifically designed for hand rehabilitation.
Methods:
The study consists of three steps, including prototype development, spasticity observation, and usability evaluation. First, we developed the prototype robot
DexoHand
to manipulate the patient's fingers based on the clinical needs and the cable-driven concept established in our previous work. Second, we applied
DexoHand
to patients with different levels of spasticity. Finally, we obtained the system usability scale (SUS) and assessed its usability.
Results:
Two healthy subjects were recruited in the pre-test, and 18 patients with stroke and four healthy subjects were recruited in the formal test for usability. The total SUS score obtained from the patients and healthy subjects was 94.77 ± 2.98 (
n
= 22), indicating an excellent level of usability. The satisfaction score was 4.74 ± 0.29 (
n
= 22), revealing high satisfaction with
DexoHand
. The tension profile measured by the cables showed the instantaneous force used to manipulate fingers among different muscle tone groups.
Conclusions:
DexoHand
meets the clinical needs with excellent usability, satisfaction, and reliable tension force monitoring, yielding a feasible platform for robot-assisted hand rehabilitation.
